POST AND/WELL AUGER.

SPECIFICATION forming part of Letters PatentNo. 284,956, dated September I1, 1883.

Application filed April 17, 1882. (No model.)

To all whom it may concern.-

Be it known that we, ELIJAH FRAZIER and NATHAN J. EDWARDS, of \Vinchester, Randolph county, and State of Indiana, have invented certain Improvements in Post and Well Angers, of which the following is a specification.

Our invention relates to that class of earthaugers which are provided with two bent blades joined together by means of a crossarm having a shaft, to which a handle is attached. These blades were formed of a thin plate of metal having a triangular form, the equal sides being arcs of a circle. having equal radii, and the body on their inner sides concived equally from the median longitudinal line to the equal sides, and secured together in such a inanner that the equal edges of one blade were overlapped at one side and underlapped at the other side by the other blade. Augers made in this way must be constantly forced into the earth by downward pressure exerted upon the handle.

The object of our invention is to obviate the necessity for this downward pressure, so that the whole strength of the operator may be used in turning the device.

To this end the nature of our invention consists of an eartlrauger of the kind described, having its blades bent in such a manner that they form a hollow screw, which, as the handle is turned, will, from. its peculiar shape, force its way in the ground, all as will hereinafter be described and claimed.

Referringto the drawings, in which like letlers of reference indicate the same part, Fig ure 1 is a side elevation of the tool; Fig. 2, an elevation of the outside of the blade; Fig. 3, an elevation of the inside of the blade, and Fig. 4 a top plan of one of the blades.

A represents the blades, B the yoke, C the stem, and D the handle, all of which, except the former, are substantially the same as those in the ordinary device, and further description of them seems unnecessary. The yoke B is attached to one side of the median line a: ;v upon a substantially flat surface, a. The side a of the plates is curved abruptly inwardly from the top a to a point, c on the side a. From the point a to the point a an inward swell, at is given to the curve, so as to pro ject the point a toward the median line 3 y of the angers. The swell a is directly opposite the flat surface a, and the points a are in the same vertical plane as the yoke B. The inner p art, a", of the blade and cutting-edge, between the points a and a is depressed to form a continuation of the groove formed by the swell (d,

so that the dirt, in ascending, will clear the yoke B. The curve givesbthe blade a screw like formation, and, when the auger is turned, draws the blades downward and forces the cut dirt upwardly between the blades.

WVhat we claim asnew is- 1. In an earth-auger, cutting-blades having the points to opposite each other and in the same vertical plane as the yoke B, and the side a, curved inwardly from the top a to a point, a, to form a groove, substantially 1' described.

2. In an earth-auger, cutting blades having a fiat and curved part, the flat part of each blade being opposite the curved part of the other blade, and the curved part approaching the median line y y. I v

3. In an earth-auger, the blade A, having fiat side a, side a, curved inwardly from the top a to a point, a, inward swell c depressed part a", forming a continuation of the swell a, and the point (0 substantially as described.
